The control of ecosystem carbon dynamics by the linkages between above and belowground processes

摘要: To grow, plants need carbon, which they can fix in photosynthesis, and inorganic nutrients, which they generally obtain from the soil, such as nitrogen and phosphate. The response of plant growth to environmental variables, such as CO2 or temperature, can be modified by the availability of these soil nutrients. Furthermore, soil nutrient availability itself can also be affected by environmental factors, such as temperature or soil moisture.
